    Tried to check spot on the BeO target but we can't see the target, only the spot. It appears that the light is out.

    1531 MCC asks if they can turn on the prebuncher in order to give us more current. We're maxed out where we are, so it's either turn on the prebuncher or start getting less current. When I asked if turning on the prebuncher would have any other effects on the beam she (Kelly) said no it would only give us more current. I said OK. -JJL
